DEVICE FOR OPERATING WINDOWS OR SHUTTERS.

Specification of Letters Patent.

Patented Dec. 31,1912.

Application filed January 15, 1912. Serial No. 671,273.

To all whom it may concern:

lie it known that l, Eznknci. VAN Noonnnx. of Boston. in the county of Suffolk and State of Islassaidiusctts, a citizen of the l nitcd titatcs, have invented a new and use ful improvement in Devices for Operating \l'iudows or Shutters, of which the following is a full, clear. and exact description. reference being had to the accompanying; drawings, forming a part of this specifica tion. in explaining its nature.

113' invention relates to an improved de vice for effecting the simultaneous control of a series or line of swinging sashes or shutters from a single point.

It comprises for its subject-matter certain elements of construction which are an 1111- provcment upon the construction shown and described in my copending application for Letters Patent of the United States, filed August 29, 1911, Serial No. 646,638, and to which reference is hereby made.

The object of my invention is to provide a device of the above character having a simple construction and one especially designed to exert a large amount of force for ccmtrolling the sashes without bending or distortion of the operating parts even though the series or line of sashes be of considerable length.

My invention can best be seen and understood by reference to the drawings, in which Figure. 1 shows the device in plan; Fig. 2 the same in side elevation; Fig. 3 a section on the line 33 of Fig. 1, and Fig. -11: is a view partly in section and partly in side elevation of an element of construction to which special reference will hereinafter be made.

Referring to the drawings l represents each of a line of sashes of which two sashes only are shown for purposes of illustration.

2 represents the wall or structure in which the sashes are arranged.

T he sashes to which my present improve ment is especially applicable are those which. turn on a horizontal axis. The sashes are accordingly shown pivotally mounted at.

-position, that is, outside the wall or structure 2 in which the sashes are arranged.

Located on the inner side of the wall or structure 2 and extending alongside sashes to be controlled, on a line about parallel with the bottoms of the sashes when in a closed position and some little distance removed therefrom is a rod or pipe 4. This pipe is supported in a fixed position by means of a series of brackets 5 which are secured to the wall or structure 2. The brackets are arranged at points between the respective sashes so as to leave a clearance along the pipe in front of each sash between adjacent brackets. Loosely arranged upon the pipe -it to slide and turn thereon are a series of collars (S, a set of two of these collars being arranged upon the pipe t in front of each of the respective sashes.

Each of the collars is provided with friction-bearing wheels 7 which bear against and run on the pipe to facilitate the movementof the collars thereon by reducing friction. In order that the collars may be easily applied to the pipe or disconnected therefrom and for the purpose also of providing for the retention of the friction-bearing wheels, the collars are made in separate parts. Each one of these parts consists of a body portion 8 which fits around the pipe 4- with ontwardly-extending flanges S) and 10 respectively, having inturncd ends 11 which butt against one an other when the two parts of the collars are applied to the pipe and separate the respective flanges thereof to form housings in which. the frictionbearing wheels 7 are contained. The combined parts of the collars are held together by means of pins 12 and 13 which pass through the flanges 9 and 10 and are secured by means of cottons 1 t. The pins pass also through the wheels 7 contained in their respective housings and provide axles on which the wheels turn, the arrangement of the parts being such of course that the wheels will bear against and run upon the pipe 4- The pins 13 which hold together the flanges 10 of the collars are provided with enlarged heads 15 reversely arranged for each set of collars, that is, each set movable on the pipe 4 in front of each sash. There are provided accordingly separate lines of the heads 15, one line located above the flanges 10 and the other below said flanges. Through these respective lines of the heads 15 extend rods 16 and 17, respectively, and which are secured to the rods by means of suitable binding screws 18. The rods 16 and 17 are longitudinally movable inreverse directions and accordin ag ly are adapted when thus moved to move the collars of each set of collars in fl'OIlt ol ever sash iu revta'se directions along the pipe -;l:. The rods 16 and 1? er;- tend to a point. i M end the line of the sash or to the place from which the sashes are controlled. There the respective rods are provided each with a rack bar 19 and operated by a pinion 20 to move the respective rods and collars carried by them longitudinallv in reverse directions. The pinion it) operated in a manner well known to those skilled in the art.

I prefer that the rods 16 and 17 shall be relatively light rods and in order that both rods may be moved in reverse directions by a pull the ends ot the respective rods opposite those bearing the rack bars are connected by means oi a llexible connection ill which runs over a pulley having any suit able fixture or support. The etiect of this arrangement is that as one of the rods pulled in o-ne direction the other rod will, through the connection 21. be pulled or drawn in a reverse direction which eliminates any danger of? the rod buckling or bending during the operation of the device as might be the case it the rods were open ated by the pinion alone and not coimeeted as aforesaid. In such case one rod would be operated by a pull in one direction as the other was pulled in a reverse direction and which might tend to distort this red it it were as light a rod as I prefer to use.

Pivotally connecting with the respective pins 13 of each set. of collars, that is the two collars for every sash, are links The pivotal connection is effected by providing each of the links with a torked end 2t which straddles the combined flanges 10 ot' the collars and through which forked ends the pins 13 extend providing pivotal hearings on which the links turn. From the points of their pivotal connection the links connecting with each set of collars extend in reverse directions inwardly in the direction or the sash and cross one another in the manner of scissors. At their point or cross ing or the point the links are pivotally connected. From this point each set of links 23 is extended to pivotally connect with links 26 which extend inwardly and are pivotally secured to the respective sides of each sash at points 2? preferably near the bottom of the sash. lit will be. observed that the links 26 are of considerable length on which account the links 23 are made curved in order that they may properly connect with the ends of the links 26 owing to the limited space between. the pipe t and the sash. The position of the pipe at relatively to the bottom of the sashes is also preferably such that the links 23 and 26 will occupy normally a substantially horizontal position when the sashes are closed.

The operation of the device is as 'lollows: rissuming the sashes to be in a closed position, the pinion 20 is turned to operate the rack bars 19 and move the rods 16 and 17 in reverse directions. The movement thus imparted to the rods causes each set of collars or those in front of each sash to move along the pipe i in reverse directions toward one another. Thereupon the links 23 which pivotally connect with the respective col lars are extended in the direction of the sashes and the force exerted thereby operating through the links 27 pushes the bottoms of the sashes outwardly and accordingly opens the sashes. This operation continues until the respective sets of collars are substantially in contact with one another which defines the :lt'ull opening of the sashes. The resistance of the sashes to opening is borne by the pipe l. in this connection it isgto be observed that the link connection between the collars and sashes is such as to hold the collars in a position where the triction bearing wheels 7 carried thereby will bear respectively against the inner and outer sides of the pipe. Accordingly as the collars are moved along the pipe toward one another to open the sashes the back thrust of the links upon the pipe causes the collars to bear with some force against the inner side face of the pipe. The friction which might thus be induced to prevent an easy movement of the collars along the pipe is (.OIDPQllSfltQCl for by those oil? the friction hearing wheels T which bear against the inner side face of the pipe.

As the sashes open and the inclination thereof becomes changed the bottom ends of the sashes will become elevated. the links and 26 then assuming a gradually increasing inclined position trom their normal position which is a substantially horizontal one when the sashes are closed as aforesaid. This movement of the links is compensated for and permitted by the collars turning slightly around the pipe as they are moved to approach one another.

The sashes are closed simply by reversing the movement of the rods 16 and 17 when the respective sets of collars are moved reversely away from one another along the pipe at which tends to retract the links and draw in the sashes. During this movement the respective sets of collars will draw along the outer edge of the pipe and the friction wheels hearing against the outer side face of the pipe will take up the friction thus induced. A reverse movement of the opera ting rods and collars is continued until the sashes are drawn to a fully closed position. As the links resume their normal position from the r inclined. position as aforesaid the collars will turn slightly upon the pipe to compensate for the changed relative position of the links.

It is apparent of course that the sashes may be held in any partially open position depending upon the relative position of the operating rods 16 and 17 and the corresponding relative positions of the collars controlled by these rods.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. The combination with a plurality of swinging sashes, of a pipe supported to extend alongside said sashes, members arranged upon said pipe and movable longitudinally thereon, a rod extending alongside said pipe and connecting with said members for etl'ecting a simultaneous movementthereot' along said pipe, and means interposed between said members and said sashes whereby the movement of said members along said pipe may be translated to said sashes for moving the same.

The combination with a plurality of swinging sashes, of a pipe supported to extend alongside said sashes, members arranged upon said pipe and movable along or around the same, means for simultaneously moving said members along said pipe in reverse directions, and means comprising link forming connections pivotally connecting with said members and with said sashes whereby the movement of said members along said pipe may be translated for moving said sashes.

The combination with a plurality of swinging sashes, of a pipe supported to extend alongside said sashes, members arranged thereon and movable along or around the same, said members being arranged upon said pipe in sets for each one of said sashes, rods extending alongside said pipe and connecting respectively with said respective sets of members, means whereby said rods may be moved simultaneously in reverse directions and like movement imtranslated to said sashes for moving the I same.
